Improvement in frame buildings

IMPROVEMENT IN FRAME BUILDINGS.

vSpecification forming part of Letters Patent No. 132,415, dated October22, 1872.

To all 'whom it may concern:

Be it known that I, LAURAMAN H. RUS- SELL, of Hyde Park, of the countyof Norfolk and State of Massachusetts, have invented new and usefulImprovement in Buildings; and do hereby declare the same to be fullydescribed in the following specification, and represented in theaccompanying drawing, of which- Figure l is a top view; Fig. 2 a sideelevation; Fig. 3 a longitudinal section 5 and Fig. 4 a transversesection of the post and two iloorin g-beams of two stories of a house orstore, with my invention applied thereto. p

It is well known that, owing to vertical shrinkage of floor-timbers whenupheld by posts or partitions, such door-timbers are lia ble to sag moreor less, and, as a consequence, cause the floors to sag and thepartition to become more or less warped or cracked. In order to preventsuch it has been customary to extend each post at its head through thetimber, and to rest the foot ofthe post next above directly upon thehead of the extension. This is generally attended with the necessity oi'making a large hole through the timber, and as a consequence the timberbecomes very much weakened thereby.

In carrying out my invention the timber is much less weakened, as,instead of one hole of large diameter, I bore a series ofsmallauger-holes down through the timber and directly over the head of thepost on which the timber is to rest, and I insert in each of such holesan iron bolt having a length equal to the depth of the timber. The lowerends of these bolts rest directly upon the head ofthe post or upon ametallic plate or cap placed on the upper end of such post. On theupper' ends of the said bolts the base of the next post is to rest, orthe partition may be erected on them or a cap resting upon them.

In the drawings, A and B denote two floortimbers, one placed over theother; one be-v longing to one door and the other to the next iloorabove. Between these door-timbers, and extending from one to the otheroi' them, is a post, C, provided at its upper and lower ends withmetallic caps or support-plates a b, arranged with respect to theHoor-timbers A B, in manner as shown. the' upper ends of a series ofround pins or bolts, c c c, extending down through the lower timber andupon a rest-plate, d, as shown. A similar series of such bolts, c c c,is arranged in the upper door-timber and so as to extend through it andrest at their lower ends upon the cap-plate of the post, all of whichbolts are separate from the posts or the cap-plates thereof. The post D,erected on the second-Hoor timber, is to rest at its (the posts) base onthe heads ofthe pins or upon a base-plate placed thereon. In case ornvertical shrinkage of the floor-timbers the posts will be upheld by thebolts and will uphold the floor-timbers so as to prevent them fromsagging and the evil consequences thereof. The great advantages of thesystem of bolts separate from each other and the posts, for givingsupport to the posts, will readily be apparent to artiiicers orcarpenters.

I claim- In combination with a floor-timber, its support orsustaining-posts, and a post to extend up from such timber, a series ofbolts separate from each other and the post or support below the timber,and also separate from the post to extend up from the timber, audarranged substantially as described and represented.
